Concord, CA has the oldest housing stock of any city we cover, and it is the biggest. Three quarters of it predates 1980, which is why a tank swap here so often turns up a shutoff that will no longer close.
West Coast Water Heaters & Plumbing works out of Pittsburg, CA and lists Concord as a service area; the routed drive is about 16 minutes. Concord is the oldest housing market on our map. The median home was built in 1970 and 35,067 of the city's 46,948 housing units, 74.7 percent, predate 1980 (ACS 2019-2023).
That age changes the job. Concord built 10,941 homes in the 1960s and 11,627 in the 1970s, so 47.9 percent of the entire city went up across those two decades. A tank set in a 1968 house has already been replaced two or three times, and each installer may have left different fittings behind, so we measure the connections on site instead of assuming them and quote the replacement from what is actually there.
Concord grants no like for like exemption. Information Bulletin IB-022, Work Requiring a Permit, revised May 18, 2023, lists Water Heater under Plumbing Permits as Yes for a new installation and Yes for a replacement, and the Building Division sits at 1950 Parkside Drive. You can read the bulletin yourself on the city's permit list. An unpermitted swap becomes the seller's problem at the next home sale.
Concord also has the highest multifamily share of any city on this site: 12,185 units, 26.0 percent, sit in buildings of five or more. Those heaters live in interior closets with a fixed vent route and a shared pan, so the replacement has to match the existing venting and clearances rather than upsize the tank. Aging supply lines behind them are a separate repipe conversation.

Concord's treated water comes from the Sacramento-San Joaquin Delta through the Ralph D. Bollman Water Treatment Plant, a Contra Costa Water District facility inside the city rated at 75 million gallons a day. Delta supply carries dissolved minerals that settle as sediment in the bottom of a tank. An annual flush is the cheapest thing a Concord homeowner can do for a heater.
Often it will not, and that is worth knowing before the truck arrives. Concord built 10,941 homes in the 1960s and 11,627 in the 1970s, which is 47.9 percent of the city. In stock that age the shutoff behind the heater is frequently original and seized. We quote the valve with the job rather than discovering it with the water already off.
We drive to Concord from Pittsburg, CA in about 16 minutes. Concord is the largest market we serve, at 46,948 housing units, and the oldest, so we spend a lot of time here on water heaters and on supply lines. Tell us the age of the house when you call and we can usually predict what we will find behind the tank.
Yes, and we prefer to. Concord's median home value is $755,900 and 38.6 percent of its occupied units are renter occupied (ACS 2019-2023), so a good share of our calls here come from a landlord or a property manager who needs a written scope and a firm number before approving work. We put the scope in writing rather than settling it at the door.
